Prevent browser extensions from triggering unwanted download prompts for `spxls-pkgdata.zip`

[aofei]

Some browser extensions are known to intercept fetch requests for files like spxls-pkgdata.zip and trigger download prompts in the browser, which is not the intended behavior, especially when the file is meant to be consumed programmatically.

To avoid this, we may need to inline the file as a Vite asset using the ?inline query.

It appears that Vite does not support inlining .zip files. Even with the explicit ?inline query, the file is still treated as an external resource and fetched at runtime.

Given this limitation, we will not inline the spxls-pkgdata.zip file for now.

We will keep this issue open in case similar scenarios arise and need to be addressed. A possible solution is demonstrated in https://github.com/goplus/builder/commit/9f7f6b545febdfa092f0a596276f0191b87e11e3, which adds a custom plugin to support inlining .zip files.
